- INSTRUCTIONS -
The NEM Long Distance Lamp Memory System is designed for communication with remote
locations up to 4,000' away, or to each elevator in a building. Sub stations are available in
surface or flush mount styles, and require a separate circuit board (PC-359B) to be added for
the call-in function. Three wires are required to each sub station.

OPERATION:
1. When a sub station places a call, the red channel LED indicator lights and a call tone rings at
the master. The tone and light will remain activated until the call is answered, which is the
primary function of the PC-359B. The LED indicator at the sub station will be lit from the time
the call is placed until it is answered.
2. If the master station is talking to another sub station, a new call from another sub station will
light the LED, but the call tone will not be heard.
3. When the call is answered, the LED on the master goes off. The person at the master uses
the push-to-talk, release-to-listen button, or picks up the handset to speak (with NEM-nA
masters). The LED at the sub station will go off when the master answers.
4. When the conversation is completed, the OFF button to the left of the station selector button
must be pressed to disengage the call.
